FLOOR AND CEILING PLATE.

Patented Oct. 29, 1912.

Application filed July 29, 1912. Serial No. 712,043.

To all whom it may concern:

Be it known that we, FRANK N. VVELLs and ALBERT R. VVELLs, citizens of the United States, residing at Southington, in the county of Hartford and State of Con necticut, have invented anew and useful Improvement in Floor and Ceiling Plates; and we do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in

Figure 1 a top or plan view of a floor or ceiling plate constructed in accordance with our invention. Fig. 2 an inside view, in the closed position. Fig. 3 a similar View, in the open position. Fig, 4 an underside edge view of one of the plates. Fig. 5 a corresponding view of the other plate. Fig. 6 a sectional view on the line a7) of Fig. 2. Fig. 7 a sectional view on the line 0-65 of This invention relates to an improvement in floor and ceiling plates for use in connection with steam and other pipes. These plates comprise two semi-circular members adapted to be placed around a pipe as it passes through the floor or ceiling.

The object of this invention is to form the members from sheet metal and to provide 'them with integral locking devices and stops; and the invention consists in the construction hereinafter described and particularly recited in the claims.

Tn carrying out our invention, we strike up two semi-circular plates 2 and 3 from sheet metal. The members are formed respectively with integral downwardly extending flanges 4, 5, tormed with notches 6 and 7 for the reception of the usual springs 8, 9, which grasp the pipe passing through the plates. At one side the plates are formed respectively with inwardly extending fingers 10, 11, perforated for the passage of a pin 12. This pin has a head 13, and on the pin between the head 13 and the finger 11, is a spring 14. The end of the pin is divided or otherwise upset so as to prevent its removal. This pin serves to hinge the two plates together. At the side opposite the fingers the plate 2 is formed with an inwardly extending latch 15, the hook 16 of which is adapted to engage with an inwardly extending catch 17 formed integral with the plate 3 and having a downwardly extending lip 18. The plate 3 is also formed with an integral stop 19 beneath which slides an arm 20 formed integral with the plate 2, and this arm is provided at its outerend witha lug 21 adapted to engage with the edge of the stop 19. Plates thus formed may be readily struck up from sheet metal.

By disengaging the latch 15 from the catch, the plates may be separated to suflicient extent to permit them to be passed around a pipe, the spring 14 yielding sufliciently for this purpose. To prevent the complete separation of the plates, the lug 21 engages with the edge of the stop 19, and the arm 20 extending beneath the stop 19 maintains the plates in proper relation to each other, the spring of the metal being sufficient to enable the hook 16 to pass over and engage with-the catch. 17 by which the plates are looked around the pipe against which they will be held by the springs 8 and 9.

We claim 1. The herein described floor and ceiling plate comprising two members struck up from sheet metal, and both formed at one side with inwardly extending fingers, a pin connecting said fingers, a sprlng around said pin and bearing against one of the fingers, the opposite edges of the plate formed one engagement thereby.

2. The herein described floor and ceiling plate comprising two members struck up from sheet metal, and both formedat one side with inwardly extending fingers, a pin connecting said fingers, a spring around said pin and bearing against one of the fingers, the opposite edges of the plate formed one with a latch and the other with a catch for with a latch and the other with a catch for engagement. thereby, one of said plates formed with a stop and the other with an arm extending betweensaid stop and the 10d plate from which it projects, said arm formed at its outer end with a lug adapted to engage with said stop,

3. The herein described floor and ceiling plate comprising two semi-circular members struck up from sheet metal said plates forming a semi-circular opening, integral flanges extending inward from .said opening, said flanges formed with notches, sprin s engaging with said notches, said plates ormed at one side with inwardly extending fingers, a
